Usage:

Engine: G3516C (S/N: DKR1-UP; RWA1-UP) G3516E (S/N: GHP1-UP) G3520C (S/N: GHE1-UP; GDB1-UP; GHC1-UP) G3520E (S/N: GHM1-UP; GHR1-UP)
Generator Set: G3516C (S/N: GZZ1-UP; GSB1-UP; TJB1-UP; TJC1-UP) G3516E (S/N: SLY1-UP; GAS1-UP) G3520C (S/N: GZL1-UP; CWW1-UP; CWY1-UP; B9P1-UP; GZM1-UP; GZN1-UP) G3520E (S/N: GZH1-UP; HAL1-UP; GZG1-UP; SXY1-UP)

Description of Change: An improved exhaust bellow is used. The inner liner of the new bellows assembly has been reduced in diameter and shortened in length. The redesigned liner will decrease the potential for rubbing between the liner and the exhaust bellow during thermal expansion of the manifold.

Adaptable To: The new 301-3073 Bellows As replaces the 227-9027 Bellows As .

Note: Do not replace the 277-4843 Bellows As with the 301-3073 Bellows As .The 301-3073 Bellows As is adaptable to the Engines and Generator Sets that are listed above. Serial number effectivity is listed in Table 1.
